Study Notes

Group Names of the Periodic Table

Alkali Earth Metals: Consist of six elements located in Group 2, known for their reactivity and occurrence in nature as compounds.
Alkali Metals: Found in Group 1, these elements are highly reactive, especially with water, and include lithium, sodium, and potassium.
Halogens: Comprise five reactive non-metals located in Group 17, which include fluorine, chlorine, bromine, iodine, and astatine, known for forming salts with metals.

Categories of Elements

Metalloids: Elements exhibiting mixed properties of metals and nonmetals, typically semiconductors of electricity, such as silicon and germanium.
Metals: Typically hard and shiny materials, characterized by good electrical and heat conductivity; they are malleable and ductile.
Noble Gases: A group of seven inert gases found in Group 18 that are characterized by their lack of chemical reactivity under standard conditions, including helium and neon.
Nonmetals: Elements that are generally poor conductors of heat and electricity, lacking metallic luster and properties.

Special Element Series

Actinides: A series of 15 radioactive elements from actinium to lawrencium, typically found in the f-block of the periodic table, showing both metal properties and significant radioactivity.
Lanthanides: A set of 15 metallic elements ranging from lanthanum to lutetium, known for similar properties, particularly high magnetic susceptibility and catalytic activity.
